I'm wondering if anyone can help, I'm stuck with the following logarithmic equation:
I can easily see why x=1 is a solution (ln(1)=0).Is this the correct procedure for finding the other solutions:
x= -2 or +2
The mark scheme for the past paper says the 2 answers are 1 and -2, but I can't see why 2 isn't a valid solution also? Also, is x=0 not a solution because ln(0) is not defined?
